Medical Images and Its Security Using Chaotic Agorithm

Abstract

Medical images are most an important role of many diseases to proper diagnosis. Medical images are essential for many diseases diagnosis, disease progress monitoring, injuries identification, etc. The medical images are recorded by using X-ray images, CT-scan images, MRI-scan images, etc. Therefore, the security of medical images is important and inferior. However, the importance of security of medical images is paramount to avoid mishandling moreover; the conventional cryptographic algorithms are unable to provide robust security. Hence, an innovative algorithm has been developed to provide robust security to medical images to avoid mishandling. Further security improvement for medical image to developed an algorithm of making a simple and effective chaotic system by using a difference of the output sequences of two same existing one-dimension (1D) chaotic maps. Simulations and performance evaluations show that the proposed system is able to produce a one-dimension (1D) chaotic system with better chaotic performances and larger chaotic ranges compared with the previous chaotic maps. The innovative algorithms have been addressed several conventional methods limitation.
